Installation, Lifting | Greenheck Fan HRE-55, HRE-20, HRE-90, HRE-45

INSTALLATION

The system design and installation should follow accepted industry practice, such as described in the ASHRAE Handbook.

Adequate space should be left around the unit for piping coils and drains, filter replacement, and maintenance. Sufficient space should be provided on the side of the unit for routine service and component removal should that become necessary.

See pages 6 and 7 for more detail on appropriate clearances.

LIFTING

Units must be lifted as it ships from the factory. All units are equipped with lifting lugs. THE USE OF ALL LIFTING LUGS IS MANDATORY WHEN LIFTING. Lifting should only be done with all access doors closed to avoid damaging the unit. To prevent damage to the unit cabinetry, use spreader bars. Spreader bars must be in position to stop cables from rubbing the frame or panels. Before hoisting into position, test lift to insure stability and balance. Avoid twisting or uneven lifting of the unit. Never lift units by weatherhoods.
